What Asan flags should I use to detect more errors? At the moment, I use ASAN_OPTIONS=detect_stack_use_after_return=1.
From Asan FAQ:
Q: Can I run AddressSanitizer with more aggressive diagnostics enabled?
A: Yes! In particular you may want to enable
CFLAGS += -fsanitize-address-use-after-scope
ASAN_OPTIONS=strict_string_checks=1:detect_stack_use_after_return=1:check_initialization_order=1:strict_init_order=1
Check https://github.com/google/sanitizers/wiki/AddressSanitizerFlags for more details on this.
In command line add these options when compiling :
-fsanitize-recover=address -fsanitize=address
When running the executables add these options :
ASAN_OPTIONS=halt_on_error=0 ./your_executable_name
These Options I tried On Ubuntu,In Windows I am still finding answer.

I'm kinda new to the world of Intel's HPC toolchain and I'm facing some troubles making even simple DPC++ application to work when gtest is used as a testing framework
This is the CMakeLists "structure" I'm following
cmake_minimum_required(VERSION 3.14)
project(foo)
set(CMAKE_CXX_COMPILER "dpcpp")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -O3 -fsycl")
# add executables
# target linked libraries
# ...
option(ENABLE_TESTS ON)
if(ENABLE_TESTS)
FetchContent_Declare(
googletest
GIT_REPOSITORY https://github.com/google/googletest.git
GIT_TAG release-1.11.0
)
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
add_subdirectory(tests)
endif()
If I remove the last block, it compiles and runs as expected, otherwise I get the following error:
CMake Error at build/_deps/googletest-src/CMakeLists.txt:10 (project):
The CMAKE_CXX_COMPILER:
dpcpp
is not a full path and was not found in the PATH.
Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_CXX_COMPILER= /usr/bin/c++
-- Generating done
CMake Generate step failed. Build files cannot be regenerated correctly.
make: *** [Makefile:2: all] Error 1
Please notice that dpcpp is correctly set, in fact I'm using Intel's devcloud platform.
Setting CXXto the output of whereis dpcpp produces the same error.
The only "workaround" (I doubt it is one though) I found is using clang++ instead (the version from Intel's llvm). Any help or suggestion is much appreciated, thanks in advance!
EDIT: after some more attempts, I noticed that if I set CMAKE_CXX_COMPILER just after fetching gtest, everything works fine. Anyway I don't understand why this happens and how can be properly fixed.
Use the path for dpcpp binary for setting the CMAKE_CXX_COMPILER instead of using"set(CMAKE_CXX_COMPILER "dpcpp")". After adding the path("/opt/intel/oneapi/compiler/2022.0.1/linux/bin/dpcpp") to the CMAKE_CXX_COMPILER, you can run the program successfully.
Please find the below CMakeLists.txt for setting the CMAKE_CXX_COMPILER:
project(foo)
set(CMAKE_CXX_COMPILER "/opt/intel/oneapi/compiler/2022.0.1/linux/bin/dpcpp")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -O3 -fsycl")
# add executables

# ...
set(ENABLE_TESTS ON)
include(FetchContent)
if(ENABLE_TESTS)
FetchContent_Declare(

Did you run the source /opt/intel/oneapi/setvars.sh intel64 script? I.e. is dpcpp on your path before running cmake?
I am testing google closure compiler on command line.
I took the latest version :
java -jar closure-compiler.jar --version
Closure Compiler (http://github.com/google/closure-compiler)
Version: v20190618
Built on: 2019-06-21 17:24
I am generating a compressed version of my javascript like this :
java -jar closure-compiler.jar my_script.js > out.js
The problem is that the generated code is bigger than the one I get when I use the online service at https://closure-compiler.appspot.com/home
I noticed that the command line version added, at the beginning, the following code :
var $jscomp=$jscomp||{};$jscomp.scope={};$jscomp.findInternal=function(a,c,b){a instanceof String&&(a=String(a));for(var d=a.length,e=0;e<d;e++){var f=a[e];if(c.call(b,f,e,a))return{i:e,v:f}}return{i:-1,v:void 0}};$jscomp.ASSUME_ES5=!1;$jscomp.ASSUME_NO_NATIVE_MAP=!1;$jscomp.ASSUME_NO_NATIVE_SET=!1;$jscomp.SIMPLE_FROUND_POLYFILL=!1;
$jscomp.defineProperty=$jscomp.ASSUME_ES5||"function"==typeof Object.defineProperties?Object.defineProperty:function(a,c,b){a!=Array.prototype&&a!=Object.prototype&&(a[c]=b.value)};$jscomp.getGlobal=function(a){return"undefined"!=typeof window&&window===a?a:"undefined"!=typeof global&&null!=global?global:a};$jscomp.global=$jscomp.getGlobal(this);
$jscomp.polyfill=function(a,c,b,d){if(c){b=$jscomp.global;a=a.split(".");for(d=0;d<a.length-1;d++){var e=a[d];e in b||(b[e]={});b=b[e]}a=a[a.length-1];d=b[a];c=c(d);c!=d&&null!=c&&$jscomp.defineProperty(b,a,{configurable:!0,writable:!0,value:c})}};$jscomp.polyfill("Array.prototype.find",function(a){return a?a:function(a,b){return $jscomp.findInternal(this,a,b).v}},"es6","es3");
I do not have such a code in my script: Where does it come from ?
how can I produce the same output as the online version ?
To get the compiler command line work as the web service, I just added an option :
--language_out=ECMASCRIPT_2015
This is likely a discrepancy between the settings on the web service and the ones you're using locally.
Have a look at a Closure Compiler: Flags and Options to see what settings you might prefer.
If you'd share your source, it'd be possible to try and help you narrow down the options.
As for the extra code, I believe it is at least partially a polyfill for Array.prototype.find (aka [].find), which I assume is in your code?
If so, that's Closure injecting code to improve your cross browser compatibility.
After going through a lot of sites about best terminal for system admins I was trying to install on Cygwin. Unfortunately, I did not find any good site with instruction about how to do it.
Is anyone done this before? Please help me with steps and packages that I need to install.
Also is there any terminals I can try (like Cygwin)?
I don't know since what version, but now you can install terminator just from the Cygwin installer. And runs great
Regards
If you don't want to use cygwinports, you can actually install all of terminator's dependencies from the cygwin installer, except for terminator itself.
In the cygwin installer select and install:
python-dbus
python-gobject
python-gtk2.0
python-vte (under GNOME tab for some reason)
GConf2
Then, pull down the latest terminator tarball from https://launchpad.net/terminator/+download and extract it somewhere. In a administrator terminal just run python setup.py install and as long as you have a running X server just running terminator will work perfectly.
The sources about how to install terminator are a bit obscures. What I did, and may help you, was this: (although I'm still having segmentation faults errors)
Update your Cygwin to the latest
Open a Cygwin terminal and run: (if you have the x86 version use that. The idea of this step is to use Cygwin Ports)
cygstart -- /your/cygwin/path/setup-x86_64.exe -K http://cygwinports.org/ports.gpg
In the section Choose A Download Site:
Add "http://downloads.sourceforge.net/cygwin-ports"
Add " ftp://ftp.cygwinports.org/pub/cygwinports"
Select another mirror close to you
Check that you have a total of three URLs selected
It may show you warning about not loading the .ini configuration but ignore them (Note: I looked for different port URLs but the official ones threw me errors and I could not pass this step, that's why I used alternatives URLs)
First, you need to install the packages for the X Window:
http://x.cygwin.com/docs/ug/setup.html
Basically they are:
xorg-server (required, the Cygwin/X X Server)
xinit (required, scripts for starting the X server: xinit, startx, startwin (and a shortcut on the Start Menu to run it), startxdmcp.bat )
xorg-docs (optional, man pages)
Also search and select the terminator package
It takes quite a while before it finishes.
Go to Start->All Programs->Cygwin-X->X Win Server (windows tool bar)
A xterm window should open. Type:
terminator
You should know have terminator with Cygwin.
Note: After I run terminator I get this error:
/usr/lib/python2.7/site-packages/terminatorlib/terminator.py:87: Warning: Attempt to add property GnomeProgram::sm-connect after class was initialised
self.gnome_program = gnome.init(APP_NAME, APP_VERSION)

Warning: python-keybinder is not installed. This means the hide_window shortcut will be unavailable
Unable to bind hide_window key, another instance/window has it.
Segmentation fault (core dumped)
I've looking to fix this issue but sadly I couldn't find anything. If you use Cygwin x86 your outcome can be different.
Hope this can help you.
I am am unable to get avr-elf-windows and WinAVR to work. I have managed to build the example supplied with avr-elf-windows (ATmega2560). But if I try and expand to use another chip or start using the WinAVR supplied packages and projects I keep getting errors I cannot work out.
Method 1:
Modify the ATmega2560 example to use the WinAVR packages.
Changed:
with Atmega2560; use Atmega2560;
to:
with AVR; use AVR;
with AVR.Atmega328p; use AVR.atmega328p;
Create a project file to include:
with "C:\WinAVR-20100110\lib\gnat\avr.gpr";
with "C:\WinAVR-20100110\lib\gnat\avr_app.gpr";
Running make I get the following error:
avr-gnatmake: "C:\WinAVR-20100110\lib\gnat\avr_lib\avr-int_img.adb" compilation error
Great, I have a compilation issue, but I cannot see the error.
Method 2:
Open the above project file in GPS. Change the build setting to be gnatmake. GPS now starts reporting errors and warnings:
Project warning: object directory "avr_lib/avr5/obj" not found
Project library directory "C:\WinAVR-20100110\lib\gnat\avr_lib\avr5\lib\" does not exist
The latter issue is very clearly the fact that I have not set up GPS correctly to tell it the values of microcontroller and architecture, but I cannot seem to find anything to resolve this.
Method 3:
To use the WinAVR set up directly using makefiles which then gives me the error:
avr-gnatmake: RTS path not valid: missing adainclude and adalib directories
If I follow the instructions I can find by searching the web I can only find details for building the required libraries under Linux.
Platform: Windows 7.
With the combination of the two answers above I have now managed to link my sample code. As to wether it will work on the Arduino, that is a different issue.
Many thanks for the help.
I have found it a bit frustrating to get this far, and I wonder if there are others out there who may just give up on Ada on the Arduino and go back to the Arduino IDE and therefore missing out on the opportunity to learn a language with more structure. There are many misleading pages out there that also do not help.
You might want to take a look in the paper Integrating 8-bit AVR Micro-Controllers in Ada. Basically you can use a GPS project file arduino.gpr like
project Arduino is
for Source_Dirs use (".", "src");
for Object_Dir use "obj";
for Exec_Dir use "bin";
for Main use ("main.adb");
package Compiler is
for Default_Switches ("ada") use ("-mmcu=avr5");
end Compiler;
package Ide is
for Gnat use "avr-gnat";
for Gnatlist use "avr-gnatls";
for Debugger_Command use "avr-gdb";
end Ide;
package Builder is
for Executable_Suffix use ".elf";
for Default_Switches ("ada") use ("--RTS=rts-zfp");
end Builder;
package Linker is
for Default_Switches ("ada") use ("obj\crtm328p._o", "-nostdlib", "-lgcc", "-mavr5", "-Tdata=0x00800200", "-mmcu=avr5");
end Linker;
end Arduino;
and you can code a spec for your ATmega328P like
with Interfaces; use Interfaces;
with System;
package ATmega328P is
-- PORTB: Port B Data Register
PORTB : Unsigned_8;
for PORTB'Address use System'To_Address (16#25#);
-- DDRB: Port B Data Direction Register
DDRB : Unsigned_8;
for DDRB'Address use System'To_Address (16#24#);
-- PINB: Port B Input Pins
PINB : Unsigned_8;
for PINB'Address use System'To_Address (16#23#);
end ATmega328P;
to be imported by your main file or libraries.
Bear with me if this isn't the immediate answer; I have only used the AVR-Ada toolchain on Linux, so we may have to iterate towards a solution unless someone else spots the problem first.
The first thing to decipher is which version of the AVR-Ada tools you have:
your project file USED to need (using avr-ada 1.1)
with "C:\WinAVR-20100110\lib\gnat\avr.gpr";
Now with avr-ada 1.2.1 you need (instead)
with "C:\WinAVR-20100110\lib\gnat\avr_app.gpr";
for building applications, and <same path>/avr_lib.gpr for libraries.
I don't believe you ever need both! And they may conflict with each other.
I don't know the state of the Windows binary build, but if you need the latest version (recommended : it's a real improvement) you may need to build it from source.
Method 1 : were you running Make from a command line? If so, I would expect to see errors in all their gory details.
Method 2 : can't help you here, I don't know GPS well enough. However I can say that on Linux there are no "avr5" folders in [wherever]/avr/lib/gnat/avr_lib. (AVR5 is correct for the 328p)
Instead there IS a [wherever]/avr/lib/avr5 containing libc and other C-related objects - including the crtm328p.o that Rego names in his linker switches, and a [wherever]/lib/gcc/avr/4.7.2/avr5 folder containing libgcc.a. You probably need to find the former and point GPS at it...
Method 3 : This looks the easiest to fix. The "gnatmake" command needs an --RTS= option pointing at the correct RTS for the 328p. This should be --RTS=rts/avr5 assuming the RTS is correctly installed.
Alternatively a full path ought to work. Here, that would be
--RTS=/opt/avr_472_gnat/lib/gcc/avr/4.7.2/rts/avr5
on Windows you may have to poke around to find the correct path.
Using Method 1 this --RTS option is automatically generated by avr_app.gpr.
It appears that having a mix of 3 or 4 tool chains installed that provide one of aspects of WinAvr, AvrAda causes significant problems (these included WinAvr, Avr-Ada, Cygwin, AVR compiler by Adacore and MinWG).
Starting with a brand new Win7 or Win8 installation perform the following:
Install WinAVR-20100110 to C:\WinAVR-20100110
Copy the content of the Avr-Ada-1.2.0_bin to C:\avr-ada-1.2.0
Add C:\avr-ada-1.2.0\bin to the PATH
Compiling the content of each of the examples in C:\avr-ada-1.2.0\share\doc\avr-ada\apps identifies that some DLLs are missing: libiconv-2.dll, libgmp-10.dll, libmpc-2.dll, libmpfr-1.dll
These can be found in a MinGW installtion.
Create a virtual machine to install MinGW on, in order to ensure it did not mess with the main PC.
Copy the missing DLLs in C:\WinAVR-20100110\bin
The example in DS1820 will not compile due to crc_lib being missing.
In order to upload to the Arduino the makefiles must be modified for your local installation, board type etc.
Do we have similar windows API of DebugBreak in Unix/ Linux. I want to debug a daemon process which should open NetBeans when DebugBreak statement is executed. Thanks in advance.
there is __builtin_trap() GCC intrinsic.
